使用命令提示符安装 Pyserial 的问题

Question

I need to process serial data using python for a project I am working on. However, the download of python 3 I have installed does not have the serial module already, so I have been working on trying to install the module.

To install the module, I downloaded PySerial 3.4, and tried to use the command prompt to install it. Specifically, I accessed the pyserial folder and found its address, directed the command prompt to that folder, and then prompted the system to install. What I typed into the command line looked as follows:

C:\WINDOWS\system32>cd C:\Users\rinty\Desktop\pyserial-3.4

C:\Users\rinty\Desktop\pyserial-3.4>python setup.py install

However, when I do this nothing occurs. No download. When I instead type

C:\Users\rinty\Desktop\pyserial-3.4>setup.py install

The install will run, but presumably not through python. When I attempt to use the command

import serial

In the python IDE I still get a "No module named 'serial'" error in response.

Is there something I am missing? How do I get python to run the setup code for pyserial? Any help is appreciated.

UPDATE

Instead of using the Windows command prompt, I tried using the Anaconda powershell. I then navigated to the pyserial folder and used the pip installation advice as follows:

cd C:\Users\rinty\Desktop\pyserial-3.4
pip install -e.

I got this response from the system:

Installing collected packages: pyserial
  Running setup.py develop for pyserial
Successfully installed pyserial

BUT, when I try to import serial in the Spyder IDE, it still tells me that no serial module can be found. Any advice?

Answer 1

Use --user Tag

Try using the --user (in the directory as follows) with the command as follows:

 python setup.py install --user 

The --user option directs setup.py to install the package (for example, foo) in the user site-packages directory for the running Python

Use pip

I prefer to use pip in such cases (I use linux). Go to the respective folder and type the following:

sudo pip install -e

This command will search for the setup.py on its own. Refer to this answer for a better understanding of how this command workssudo pip install -e

Use PyCharm instead of Spider

Since I had been using Linux for so long, I was very inexperienced with windows python. --user worked for me in most cases. But, many such problems can be solved with PyCharm , especially those that arise due to different versions of python on the same machine. You can choose from the UI itself which python-interpreter you want to use and you can uninstall modules for that particular version. You can even create virtual environments.

Following are the steps:

1) Install PyCharm https://www.jetbrains.com/pycharm/download/#section=windows

2) Go to File Menu. Click on settings

3) Chose the Interpreter

4) Install module:

Let me know if this doesn't work :)
